Lapis Lazuli

Lapis lazuli is an opaque ornamental stone prized for its rich royal-blue color. It is a rock composed of several minerals, rather than a single mineral.

• Main component: Lazurite
• Common inclusions: White calcite and gold-colored pyrite
• Typical color: Deep blue to violet-blue
• Hardness: About 5–5.5 on the Mohs scale
• Major sources: Afghanistan, Chile, Russia, Pakistan, and parts of the United States

Appearance and value

Fine-quality lapis lazuli usually has an intense, even blue color, little visible white calcite, and small, attractively scattered pyrite flecks. Pyrite can resemble tiny pieces of gold, but excessive pale calcite may lower the stone’s value. Genuine lapis is normally opaque.

History and uses

Lapis lazuli has been used for thousands of years in jewelry, carvings, seals, decorative objects, and mosaics. Ground lapis was historically used to produce natural ultramarine, a valuable blue pigment employed in manuscripts and paintings.

Symbolism

Various traditions associate lapis lazuli with wisdom, truth, confidence, and communication. These are cultural or spiritual beliefs rather

Lapis lazuli is commonly associated with September as a traditional or alternative birthstone.

The principal modern birthstone for September is sapphire, but lapis lazuli is often included in older and alternative birthstone lists. It is also sometimes associated with December, depending on the tradition.
